I was playing Janes F/A-18 game and the temp. of the graphic card went high, so I tok a big fan we have home and opend up my kabinet door to my inner pc stuff, and checkt if the temp. gets lower lol
My temp before was 55 to 56
after I added the exptra fan hehe 
down to 46 - 47
but the main problem is when playing games like Half Life 2 and FarCry after playing 15 to 30 mins the pc restarts ! on my latest updated graphic card update driver:(
